If you mean RCS, end-to-end encryption is not part of the standard, it is a non-standard extension supported only by the google messages app https://support.google.com/messages/answer/10262381?hl=en

Does RCS need E2E to be better than SMS when it comes to privacy/security?

[dwaite]

IMHO profiled RCS is notably worse than SMS for privacy, because the vast majority of RCS servers are hosted by Google.

SMS can be read but it is still at least somewhat decentralized. It isn't being funneled to a single party whose business model is profiling users.

Yes, it does. RCS without E2E is following the SMS model and putting your telco in charge. It uses transport encryption but that is basically meaningless when every relay sees the entire contents of the message.

Yeah anything that's not E2E encrypted is pretty useless for privacy/security these days. Might as well just use DMs on reddit, twitter, etc if you don't care about E2E
